Radio Frequency Interference

Personal Daq User’s Manual

887095

Troubleshooting & Customer Assistance 7-1

Personal Daq hardware complies with the limits for a Class B digital device according to FCC rules and CE
specifications. These limits provide reasonable protection against harmful interference in a residential
environment.

If not installed or used correctly, this equipment can radiate radio frequency energy and interfere with radio
communications. You can determine if the interference is caused by the Personal Daq system by discon-
necting and then reconnecting the Personal Daq while observing the effect on the interference.

You can often correct radio interference by one or both of the following measures:

•

Antenna Adjustment:

Reorient the receiving antenna.

•

Spatial Separation:

Increase the separation between the Personal Daq equipment and the

receiver of the device experiencing interference.

If the problem cannot be resolved, consult an experienced radio/television technician for help.

Electrostatic Discharge (ESD)

CAUTION

The discharge of static electricity can damage some electronic components.
Semiconductor devices are especially susceptible to ESD damage. You should
always handle components carefully, and you should never touch connector pins
or circuit components unless you are following ESD guidelines in an appropriate
ESD controlled area. Such guidelines include the use of properly grounded mats
and wrist straps, ESD bags and cartons, and related procedures.
